Chemistry and biological activity of triterpenoid glycosides from Medicago sativa.
TLDR
Ten triterpenoid glycosides have been isolated from the roots of Medicago sativa L. (Leguminosae) including eight new glycoside and two previously known, medicagenic acid 3-O-beta-D-glucopyranoside and hederagenin 3- O-[alpha-L-arabinopyranuside] and four new saponins. Expand
Tripenoid glycosides of alfalfa. VII. Medicosides E and F
Two hederagenin glycosides — medicosides E and F — have been isolated from the roots ofMedicago sativa L. (Leguminosae). Medicoside E has the structure of hederagenin 28-O-β-D-glucopyranosideExpand

Secondary-emission mass spectrometry of hederagenin glycosides and medicagenic acid glycosides
The secondary emission (SE) spectra of six glycosides of medicagenic acid (MA) and of hederagenin have been studied. The (M + H)+ ions were observed in the secondary ion spectra (LSIMS) of mono- andExpand

On the basis of chemical transformations and with the aid of physicochemical results, the structure of glycoside I isolated from the roots of the plantMedicago sativa has been established asExpand
Triterpene glycosides of alfalfa VIII. Medinoside E from the leaves
From the leaves ofMedicago sativa L. (Leguminosae) we have isolated the glycoside soyasapogenol B — medinoside E. Medinoside E has the structure of olean-12-ene-3β,22β,24-triolExpand
